Laser projection display technology (LPDT), as next-generation visual system, has been prized for the ultrawide color gamut and operational stability. However, thermal degradation under laser irradiation and the scarcity of efficient narrow-band emitters are always challenging in LPDT. Herein, a double-sapphire-sandwiched phosphor-in-glass film (PiGF) based on commercial red-emitting K 2 SiF 6 :Mn 4+ and green-emitting β -SiAlON:Eu phosphors, is designed and prepared by a rapid sintering method. The as-prepared PiGF demo can achieve high luminous flux of 3765 and 1365 lm, respectively, and the ingenious cooperative rotating dynamic heat dissipation mechanism maintains temperatures at 60 °C even under 14 W mm −2 laser irradiations, thereby preventing degradation. Once being integrated into a multicolor phosphor wheel, it generates noncoherent white light covering 125% of the Rec.709 color standard representing an ultrawide color gamut. This work provides an advanced phosphor material platform enabling high-brightness, reliable LPDT for next-generation projectors and televisions.

All-solid-state lithium batteries (ASSLBs) employing Li-rich layered oxide (LLO) cathodes are regarded as promising next-generation energy storage systems owing to their outstanding energy density and intrinsic safety. Polymer-in-salt solid electrolytes (PISSEs) offer advantages such as high room-temperature ionic conductivity, enhanced Li anode interfacial compatibility, and low processing costs; however, their practical deployment is hindered by poor oxidative stability especially under high-voltage conditions. In this study, we report the rational design of a bilayer electrolyte architecture featuring an in situ solidified LiClO4-doped succinonitrile (LiClO4–SN) plastic–crystal interlayer between a Li1.2Mn0.6Ni0.2O2(LMNO) cathode and a poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)-based PISSE. This PISSE/SN–LiClO4configuration exhibits a wide electrochemical stability window up to 4.7 V vs. Li+/Li and delivers a high ionic conductivity of 5.68 × 10−4S cm−1at 25 °C. The solidified LiClO4-SN layer serves as an effective physical barrier, shielding the PVDF-HFP matrix from direct interfacial contact with LMNO and thereby suppressing its oxidative decomposition at elevated potentials. As a result, the bilayer polymer-based cells with the LMNO cathode demonstrate an initial discharge capacity of ∼206 mAh g−1at 0.05 C and exhibit good cycling stability with 85.7% capacity retention after 100 cycles at 0.5 C under a high cut-off voltage of 4.6 V. This work not only provides a promising strategy to enhance the compatibility of PVDF-HFP-based electrolytes with high-voltage cathodes through the facile in situ solidification of plastic interlayers but also promotes the application of LMNO cathode material in high-energy ASSLBs.

The flavor of cigar smoke directly influences the consumer’s willingness to purchase. However, the analysis of cigar smoke was lack. In this research, a total of 235 volatile compounds were identified by GC×GC-TOFMS in cigar smoke from Yuxi, Dehong and Pu’er regions of Yunnan, including 72 alkenes, 47 aromatic hydrocarbons, 42 heterocyclics, 28 ketones, 8 alcohols, 4 aldehydes, 3 esters, 13 phenols, 5 acetonitrile and 13 others. ROAV analysis indicated that o-cresol, guaiacol, 2,6-dimethyl-phenol, 4-hydroxy-3-methoxystyrene, (E,E)-2,4-hexadienal, butylbenzene, naphthalene, nicotine and D-limonene might be the key flavor compounds. By OPLS-DA, 2-methyl-pyridine, 2,4-dimethylfuran, 2-carene, 13-heptadecyn-1-ol, 1-ethyl-2-methyl-benzene, 2,3,5,8-tetramethyl-1,5,9-decatrien, 1-ethyl-4-methyl-benzene, β-elemene, methyl isobutyl ketone and 3-methylcyclopentanone were found to be the differential volatiles distinguishing samples from different areas. Eventually, 5 groups of potential flavor precursors were summarized and identified (cembranoid, phenylalanine, chlorophyll, carotenoid and reducing sugar). This research has provided theoretical guidance for the improvement of flavor quality of cigar smoke in Yunnan.

In this work, a novel three-step method was used to modify the surface of silicon quantum dots to synthesize amphiphilic silicon quantum dots (A-SiQDs) with higher interfacial activity. The particle size of A-SiQDs was only 3.5 nm. By adding a small amount of dodecyl dimethyl betaine (BS-12), the performance of A-SiQDs was further improved. Through particle size and zeta potential testing, it can be seen that the mixed system of A-SiQDs and BS-12 had good temperature and salinity resistance, and can be stable at 120 °C and 50,000 mg/L NaCl. Meanwhile, the mixed system exhibited superior interfacial activity compared with individual A-SiQDs and BS-12. The mixed system can lower the interfacial tension from 32.15 mN/m to 1.82 mN/m and transform the rock surface from an oil-wet to a strong water-wet state. This ensured the excellent imbibition ability of the mixed system, which can increase the oil recovery to 35.7 %. Finally, from the perspective of force, the influence of nanofluids on oil stripping and migration was analyzed to reveal the imbibition mechanism. This paper proposes a facile three-step method for synthesizing A-SiQDs, and also provides a novel nanomaterial for high efficiency imbibition in low-permeability reservoirs.

Intermetallic phases with atomic ordering are highly active and stable in catalysts. However, understanding the atomistic mechanisms of disorder-to-order phase transition, particularly in multi-component systems, remains challenging. Here, we investigate the atom diffusion and phase transition within Pd@Pt-Co cubic nanoparticles during annealing, using in-situ electron microscopy and ex-situ atomic resolution element analysis. We reveal that initial outward diffusing Pd partially substitutes Pt, forming a (Pt, Pd)-Co ternary system in the surface region, enabling the phase transition at a low temperature of 400 °C, followed by shape-preserved inward propagation of the ordered phase. At higher temperatures, excessive interdiffusion across the interface changes the stoichiometric ratio, diminishing the atomic ordering, leading to obvious change in morphology. Calculations indicate that the Pd-substitute in (Pt, Pd)-Co system leads to a significantly lower phase transition temperature compared to that of Pt-Co alloy and thus a lower activation energy for atomic diffusion. These insights into atomistic behavior are crucial for future design of multi-component systems.

Background: Cholesterol gallstone disease (CGS) is often accompanied by gallbladder contraction dysfunction and chronic inflammation, but effective therapeutic options remain limited. This study investigates whether a low-intensity pulsed ultrasound (LIPUS) treatment can improve gallbladder motility and alleviate chronic inflammation while exploring the underlying mechanisms. Methods: Gallbladder motility was assessed through in vitro and in vivo contraction tests, while bile condition was evaluated by observing bile crystal clearance. Tissue analysis and Western blotting were performed to examine the expression of the cholecystokinin A receptor (CCKAR) and α-smooth muscle actin (α-SMA) as markers of gallbladder smooth muscle health and the inflammatory microenvironment. Blood cholesterol levels were measured via biochemical assays. Results: LIPUS treatment obviously enhanced gallbladder contractility in response to CCK-8 stimulation and accelerated bile crystal clearance. It also reduced inflammatory cell infiltration and tissue edema, and promoted new capillary formation in the gallbladder, mitigating the progression of CGS. Furthermore, LIPUS restored CCKAR expression and improved the thickness of the gallbladder smooth muscle layer, providing a structural basis for increased smooth muscle contractility. Conclusion: LIPUS improves gallbladder motility and reduces chronic inflammation in CGS by enhancing CCKAR expression and smooth muscle integrity. These findings highlight the potential of LIPUS as a non-invasive therapeutic approach for managing CGS.

The escalating obesity epidemic poses serious public health challenges, requiring the development of effective therapeutic strategies. In this study, we aimed to determine if recombinant glycoprotein hormone β5 (GPHB5) protein, particularly in the hybrid form with glycoprotein hormone α2 (GPHA2) (recombinant corticotroph-derived glycoprotein hormone, rCGH), can alleviate obesity in the genetically obese mice, ob/ob . Six-week-old male ob/ob mice were intraperitoneally injected for four weeks with rCGH (10 mg/kg) treatment. Body weight, fat mass and lean mass as well as energy expenditure were evaluated. Blood samples were collected to assess circulating concentrations of triiodothyronine (T3) and thyroxine (T4). Glucose and insulin tolerance tests were also conducted. rCGH significantly decreased body weight and fat mass, stimulated energy expenditure without alterations in food consumption, induced lipolysis and browning of white adipose tissue (WAT) by activating cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling pathway. The treatment with the recombinant protein also led to marked reduction in hepatic steatosis, improved glucose tolerance and insulin sensitivity, and reduced triglycerides (TG), and total cholesterol (T-CHO) levels in ob/ob mice. In conclusion, rCGH attenuated obesity and alleviated metabolic syndromes in ob/ob mice, and it may represent a promising polypeptide-based drug candidate in treating obesity and obesity-related complications without interfering energy intake.

Defect engineering of metal organic frameworks (MOFs) is an emerging effective approach for manipulating their microporosity structure. They are very promising but challenging to achieve significant gas separation performance improvements for mixed matrix membranes (MMMs) fabrication. Herein, we propose a novel thermal induced in-situ defect engineering strategy of ZIF-8 in MMMs by carefully post controlled annealing (above polyimide matrix T g and below ZIF-8 T d ). Attractively, the thermal-triggered polyimide matrix (P84 HT) crosslinking repairs interfacial voids between ZIF-8 and P84 HT. The resulting advanced MMMs exhibit more gas sorption sites and diffusion pathways owing to the missing Zn-N bond of ZIF-8, while exciting enhancement of H 2 /CH 4 and H 2 /N 2 separation performance is obtained compared with the pristine P84 HT membrane. Furthermore, after in-situ defect engineering at 400 °C, the H 2 permeability of the advanced MMMs with 20 wt% ZIF-8 loading is 123.8 Barrer, 19.4 times higher than the pristine P84 HT membrane (6.4 Barrer), while the H 2 /CH 4 and H 2 /N 2 selectivity almost remains essentially unchanged. More importantly, this facile but very effective method demonstrates a new direction to regulate structure of polyimide/MOFs based MMMs for gas separation.

WO3 with nanocrystal-in-glass (nanocrystal-embedded amorphous matrix) characteristics is recognized as a highly promising electrochromic material. The demand for flexible and large-area electrochromic technologies is pushing the advancement of low-temperature and large-scale processes for WO3 thin films. This study presents a functional ink designed for the low-temperature preparation of WO3 thin films using blade-coating technology, enabling scalable and cost-effective production. The optimized WO3:Ti-PEDOT hybrid electrochromic thin film demonstrates a high light modulation rate of 86.05% (@ 633 nm), a coloration efficiency of 54.1 cm2 C–1, an outstanding cycle stability exceeding 1000 cycles, and an ionic diffusion coefficient of 3.69 × 10–8 cm2 s–1. One reason for the remarkably improved electrochromic performance is the synergistic effect of the nanostructured WO3 glass-nanocrystal composites induced by Ti doping and the enhanced electrochemical reaction kinetics facilitated by the use of poly(3,4-ethylenedioxythiophene) (PEDOT), a conductive polymer, as a binder. This work demonstrates a feasible and cost-effective method for producing WO3-based films for electrochromic smart windows, serving as an alternative to the existing vacuum-based WO3 thin film production methods.

Phosphor-in-glass (PiG) is a promising all-inorganic color converter for high-power solid-state lighting applications. However, strong interfacial diffusion degrades the phosphor performance and impedes the progress of PiG-based white light-emitting diodes (WLEDs) in achieving high brightness and efficacy. In this study, a glass matrix (SiO2–B2O3–Al2O3–CaO-Y2O3–Na2O) designed specifically for Y3Al5O12:Ce3+ (YAG:Ce3+) phosphors was proposed aiming to suppress interfacial diffusion. The glass design principles involved confining ionic diffusion through modulation of the glass coordination structure and reducing interfacial concentration gradients through introduction of phosphor elements into the glass matrix. Consequently, interfacial diffusion in the synthesized YAG:Ce3+-PiG was effectively suppressed, with an interfacial reaction layer thinner than 55 nm. The internal quantum efficiency of YAG:Ce3+-PiG was sustained at 97%, while its fluorescence lifetime decreased by only 0.6 ns compared to that of the original phosphor. The WLED fabricated with YAG:Ce3+-PiG exhibited a high luminous efficacy of 122 lm/W under a high input power of 3 W. Additionally, simultaneous incorporation of YAG:Ce3+ and CaAlSiN3:Eu2+ phosphors further enhanced the white-light quality of the WLED, achieving a high color rendering index of 92.6. The findings underscore the importance of rational glass composition design for PiG composites and will facilitate the development of efficient high-power WLED devices.

4-Aminophenol (4-AP), a crucial organic intermediate in the synthesis of acetaminophen, poses significant toxicity and potential environmental and health risks. Titanium dioxide@ titanium-based metal–organic frameworks (TiO2@Ti-MOFs) form a three-dimensional heterogeneous composite structure by covalently binding to the surface of 2D transition metal carbides and nitrides (MXenes). The synergistic effect between the porosity of titanium-based metal–organic frameworks (Ti-MOFs) and the layered structure of MXenes provides abundant adsorption sites, effectively enriching the target molecule 4-AP and enhancing the sensor's selectivity. The high conductivity of MXenes, combined with the semiconductor properties of TiO2@Ti-MOFs, accelerates electron transfer on the electrode surface, resulting in an increased response current and improved sensitivity and detection range. The detection range of the TiO2@Ti-MOF/MXene electrochemical sensor spans from 0.5 to 50 μM, with a detection limit of 0.16 μM. This sensor is effectively applicable for detecting 4-AP in real water samples, such as tap water and Qingshan Lake water, demonstrating satisfactory recovery.

Perovskite quantum dots have become a research hotspot due to their excellent luminescence properties such as high PLQY and narrow half-wide peaks, but the complex preparation process and poor stability are the main problems affecting their application. In this study, CsPbX 3 (X = Br,I) quantum dots were uniformly grown in situ in the inner pores of SiO 2 aerogels by molten salt method in the case of all inorganic ligands, so that perovskite quantum dots can be generated and effectively protected at the same time. The CsPbBr 3 @SiO 2 aerogel and CsPbI 3 @SiO 2 aerogel composites exhibit highest luminescence intensities at 523 nm and 680 nm respectively, and have narrow half-peak widths (20 nm and 40 nm). At the same time, they have enhanced stability under air, UV lamp and high temperature. After 7 days of exposure to air and UV lamp, the PL strength of the CsPbBr 3 @SiO 2 aerogel composites remained 74.5 % and 133 % respectively. Finally, the green and white LED devices have been successfully constructed by laminating CsPbX 3 @SiO 2 aerogel composites on the surface of a 460 nm chip. These characteristics have laid a good foundation for the application of LED devices, and at the same time, CsPbX 3 @SiO 2 aerogel composites show great potential in luminescence applications.
